Definitions

  • This invention relates to a method for controlling a door in an automatic door system, and more particularly to a method for controlling the opening/closing operation of a door in an automatic door system when an accidental condition of the door occurs.
  • a conventional automatic door system when there is a human-body detection signal in a normal operation of a door of the system, the door thereof conducts its high-speed opening operation until it reaches a deceleration point thereof in its opening operation, and thereafter conducts its low-speed opening operation until the door reaches its stop point in the opening operation thereof (hereinafter referred to as the opening-stop point).
  • the opening-stop point After the door's arrival in the opening-stop point, the door conducts its high-speed closing operation until it reaches a deceleration point thereof in its closing operation. After the door's arrival in the deceleration point, the door conducts its low-speed closing operation until it reaches a stop point thereof in its closing operation (hereinafter referred to as the closing-stop point).
  • the door conducts its low-speed opening/closing operation to move to its opening-stop point or to its closing-stop point, so that the opening-stop point or the closing-stop point of the door is checked and then a normal opening/closing operation of the door is conducted.
  • the low-speed opening/closing operation of the door is repeated before completion of a check on the opening-stop point or the closing-stop point of the door, so that, in case that a human-body detection signal is inputted before completion of such check, the low-speed opening/closing operation of the door is repeated to delay a person going through the door opening.
  • Such delay is not preferable in use and constitutes a disadvantage inherent in a conventional method for controlling the automatic door in its opening/closing operation when an accidental condition of the door occurs.
  • a deceleration point is established according to a position of the door at a time when such accidental condition occurs; and, in case that a human-body detection signal is inputted, the door moves at a high speed to the above deceleration point so that the door is controlled in its opening/closing operation to swiftly conduct its opening/closing operation even when the accidental condition occurs, so that a person may immediately go through the door opening while the door is prevented from colliding with the obstacle at the accidental condition occurring point.
